Development status of machining

With the rapid development of modern mechanical processing and the rapid development of mechanical processing technology, many advanced mechanical processing technology methods have slowly emerged, such as micro-machining technology, rapid prototyping technology, and precision ultra-precision processing technology.

With the development of Micro/Nano Science and Technology, micromachines characterized by their tiny shapes or small operating scales have become a high-tech technology for people to understand and transform the micro world . Because of its characteristics of being able to operate in a small space without disturbing the working environment and objects, micromachines have broad application potential in the fields of aerospace, precision instruments, biomedicine, etc., and have become an important means of nanotechnology research. It is highly valued and ranked as the number one key technology in the 21st century.

Rapid prototyping machining technology
Rapid prototyping technology was developed in the 20th century, and samples or parts can be quickly manufactured based on CAD models. It is a material accumulation processing manufacturing method, that is, three-dimensional forming is completed through the orderly accumulation of materials. Rapid prototyping technology integrates modern scientific and technological achievements such as CNC technology, material technology, laser technology and CAD technology, and is an important part of modern advanced machining technology.

Precision ultra-precision machining technology
Precision and ultra-precision machining are an important part of modern mechanical manufacturing technology, and are one of the important indicators to measure the level of a country’s high-tech manufacturing industry. Since the 1960s, with the development of computers and information technology, higher requirements have been placed on manufacturing technology, not only to obtain extremely high size, shape and position accuracy, but also to obtain extremely high surface quality. It is precisely in this market demand that ultra-precision machining technology has been rapidly developed, and various processes and new methods are constantly emerging
